A medium-sized Newtonian system telescope with moderate aperture, well suited for planetary observations as well as for observing nebular objects. Hassle-free to use, stable, producing sharp and clear images with minimal coma, it is a great solution for beginning astronomy enthusiasts.
Optical System
This is a telescope with a relatively long focal length and moderate focal length. In this case luminosity is f/8 which virtually eliminates the basic drawback of Newtonian telescopes, which is coma. The images given at a moderately large aperture (15cm) are calm, this telescope is less sensitive to bad seeing than 20-40cm telescopes.
Mounting
The telescope is suspended on an azimuthal Dobson mount, which allows easy rotation in azimuth and elevation. The telescope is mounted on two sides in a forked mount, while the entire top of the mount rotates at the base. With a very low center of gravity and made of fairly rigid materials, the telescope is suspended in a much more stable manner than parallactic mounts.
Extractor
The telescope is equipped with a 2" eyepiece extractor with a reduction to 1.25". It is a Rack&Pinion type focuser, i.e. a classic focuser built around a rack and pinion.
